This builds a three-option plumbing proposal from a single base price. It takes your Good option, the straight replacement, and uplifts it by the percentages you set for Better and Best, then shows the deposit on the middle option and what it comes to per month over a financing term as straight division. Three options priced from one base is how a water heater proposal sells the tankless without arguing for it: the customer picks, and the middle option is where most of them land.

Good is the honest baseline, not the loss leader

The Good option is the job priced properly with the flat rate math and the estimate on this site: a like-for-like replacement at your real rate and markup. It is not a low number designed to be rejected. A customer who chooses Good should get a job you made money on, because a proposal built on a fake baseline is a proposal that costs you the trust that sells the upgrade.

Better is where the margin lives

Better adds the things the property actually needs: an expansion tank, new shutoffs, a pan and drain, a higher-grade fixture. Price it as an uplift on Good so the increment is visible and defensible. Most customers choose the middle option; the page puts the deposit and the monthly figure on it for that reason.

Best is the option you would install in your own house

Tankless with recirculation, whole-house filtration, a full repipe alongside the heater. Some customers want it, and a proposal without it never finds them. Price it as its own uplift on Good and let it sit at the top of the page. The page states how long the proposal is valid so the prices do not follow the supply house upward for free.

Plumbing proposal template: common questions

Is this a free plumbing proposal template?

Yes: the three prices, the deposit and the monthly figure are computed here for free with no account. RoughInDesk Pro turns them into the proposal document with your name and license on it, saves it against the customer, and lets you compare good, better and best on saved scenarios.

What is the monthly figure based on?

Straight division of the Better price by the term you enter, with no interest, so the customer sees the order of magnitude. If you offer financing through a partner, their quote replaces it; the page does not invent an interest rate.

How long should a proposal be valid?

Long enough for the customer to decide and short enough that the supply house cannot move your cost first. Thirty days is common; the page prints the figure you enter.
